TELEGRAP'HIC TYPE-WRITER.

SPEGIFICATiON forming part of Letters Patent No. 655,249, aateunu ust 7,1900.

Application filed August 29, 1898.

To all whom it may concern:

Be it known that I, REINHOIQD KiiBLER, a subject of the King of Prussia,German Emperor, residing at Berlin, Germany, have invented a certain newand useful Improved Telegraphic Type-Writer, of which the following is afull, clear, and exact description.

The present invention relates to a telegraphic type-writer the effect ofwhich is the same as the ordinary type-wheel type-writer.

The invention involves mainly the follow ing principle: Electricimpulses produced by means of a contact-bar and metallic pointer formingthe sender are transmitted to the receiving apparatus and produce therotation of a type-wheel, the type of which after being adjusted to theoperative or printing position is caused to efiect the impression at themo ment a somewhat-longer electric impulse or a longer interruption ofthe electric current is effected at the sender end. As soon asthe signhas been printed the type-wheel is returned to its initial position.

' In order to render the present specification more easily intelligible,reference is had to the accompanying drawings, in which similarcharacters of reference denote similar parts throughout the severalviews.

Figure 1 is a representation in plan view of the sender device; Fig. 2,adiagrammatical representation of the receiver apparatus; Fig. 3, a planview of a part of the latter apparatus,

in connection therewith; and Fig. 4, a longitudinal vertical sectionthrough the device shown at Fig. 1.

The sender device, Fig. 1, consists of a metal bar 13, mounted in aguide-board of ebonyA and provided with eleven pieces of ebony C C 0 letinto the same at equal distances apart and being flush with theremaining Inetallic'surfaces c o c a stop D being provided at one endnext to the'strip C. The signs tobe transmitted are arranged after themanner of a type writer along both edges of the ebony base-plate A. Onewire of the line-battery LB is secured, by means of a means of the metalsleeve G, the said pointer being provided with a handle or holder Hafter the manner of a pen or pencil. The

line-wire 1 2 3 lis attached at one end to the (No model.)

sender apparatus by a clamping-screw I and at the other end to thereceiver at at to one end of the coil of a relay-magnet RM, Fig. 2, theother end of which is connected with the earth.

From the construction of the keyboard of the sender apparatus it will beevident that if the pointer is placed on the strip of metal 0representing the letters g at one side and the strip 0 will produce asomewhat-longer breakage of the circuit, 0 being non-conducting, and inthe latter at c a somewhat- :longer closure of the circuit will result.This is due to the fact that when the pointer is moved somewhat quicklyfrom C to O or c it will be arrested suddenly by the stop D and willnecessarily remain a moment longer on the end strip, since the suddenarrestwill cause a slight delay in removing it. Accordingly in the firstcase the armature R of relay RM will be released for a longer period,and in the second case it will be attracted for a correspondingly-longerperiod. Thus it will be clear that if the pointer is placed on one orthe other strip of ebony or metal and passed along over the others tothe stop D the fin'al result after a certain number of impulses willvary according to whether the pointer finally reaches a conducting ornonconducting strip-1}. 6., according to whether the pointer is passedalong the upper or lower edge of the base-plate A. Thus each of thestrips 0 or 0 will be capable of transmitting two different signs.

14 of a local battery, which circuit is closed or otherwise according tothe operation of the line-wires.

A is the spring-retracted pivotally-mounted armature of the magnet TM,and mounted at its forward end are two pawls L and M, adapted to engageat diametrically-opposite points the teeth of a ratchet-wheel N,revolubly mounted in proximity to a shaft close to the type-wheel shaft.These pawls are so arranged that when the armature A is attracted Themagnet TM ofthe type-Wheel is arranged in the circuit5 6 7 to the pawlMwill turn the Wheel N half a tooth, the pawliL slidingover the lasthalf'of its tooth iilto engagement with the next tooth, so that on thearmature being released the pawl L will operate to turn theratchet-wheel N in the same direction half a tooth further, the pawl Mthis time sliding over the last half of its tooth into engagement withthe next. The ratchet-wheel shaft carries a gear G adapted to engage apinion H of the typewheel shaft, and the two pawls L and M are connectedby aspringBt.

From the aboveitwill beclear that each i111 pulse which is conveyedtoth'e magnet TM will cause the type-wheel to be rotated a distancecorresponding to one tooth of the ratchetwheel, but-two types ofthe-type-wheel.

The telegraphic signs are arranged ontwo typeewheels OandO thosesigns'on O cor-- responding tothe sign on the sender-board, Fig:'1,. ateit-henend of the interruptingstrips thereof, while. those onvOcorrespond tothe signson the sender-boardwhich' are:

At each i impulse and ateach interruptionof'the -current, as'mentioned previously, the type-wheel willi berotated to the extent of one type.

'A pin P is mounted on the armatureA-,

The negative pole of thisbattery is connected to a fiat spring U, restin g on a small metallicdisk T, fast on the type-wheel shaft. Thus a local circuit willf-eXist-from-the battery-OB, through the disk T and the body of theapparatus to the armature A and along-thesame to the contact-pin P,spring Ror Q, post S, and back to the batltery. A second disk V ismounted on the type-wheel shaft and providedwitha contactitooth Z,with-which a flat'spring Xis in contact, thesaidspring, like U, being inconnection with the negative pole of the local batrtery. A thirds-pringiy, which iS iD-CODHLOU lwith-thebody oftheapparatus through its@contactwithrdisk M Fig, 3, .ofthety pewhaft, isconnected to one endvofthecoilofthe imagnet AM, the other end of which leads ito. thepositive pole of the local battery OB. flWhen thetype-wheelshaft isinitsfinitial po- Esition, V the flat=springs Urand X rest :on piecesEofebonylet into the-peripheries of'thetdisk's and V and designated by Wand'Z, respecitively, and the circuit 15 -tor22,.which effects ftheprinting, andthe circuit 251028, 19, 18,- 17,

@however, as the electromagnetTMoomeainto Zoperation the current willpass-to from- }jthesfirst impulse; bu-t-itwill not passitol'DM funtilthesecond movementof the armature;

A in. the oppositedirection', owing'tothefact Ijthat-the. width of thepieces 'of- V ebony; Z" and on" the disks V and-T, on which thetfiat.springsX and U rest, is:in the first case less jthan the path ofmovement described; by the grespective disk on one-movement ofthe'armature, andiin the :secondcasegreater than.

thefirst and less than-the space-describedby the disk,owingtothesecondswing of; the farmature-zle. than the-path described bythe disks'initwo movements-of the armature.

The armatures' ofboth magnets DM-and AM are adj usted to turnsomewhatslowly, so that they will not be attracted by'theshort localcurrents. closed inthe receiving apparatus-by the movement of thepointer atthesender end. The printing-magnet willflnot attract itsarmature until the longer impulse is-im--- parted, asexplained-i. e.,after the-type has ibeen-adjuste'd toimpress the strip: When theprinting-magnet has attracted itsarmature H the arm-J. willdepressrtheend L- of the double-arm lever L M, the-latter armof which carries theprinting-roll K,.and' will slide out of engagement with thesameat themoment the roll K has raised the paper'strip against-the type,.thusallowing the printing roll to fall: backsto its initial positionbygravity or by any suitable spring device. Immediately after this has;taken place thedownwardly-extendingaarm N engages-theiupper end ofalvertically-guided bar 1?, thezlower end'of whichrrestson thehorizontal armsoftwo" pivotally-mounted bell crank levers F F,havingtheir upwardly-extending arms in engagement with downwardly-extendin gpins B B fast on the pawls L and M. This action of the bar P releasesthe ratchet-wheel N from the pawls and allows the same, and with it thetype-Wheel and shaft, to return to their initial position under theinfluence of a spring W, Fig. 3. The return movement of the type-wheelshaft will interrupt the circuit of the local battery, so that theprintingmagnet will release its armature H which on rising will turn theratchet-wheel W by means of the pawl V, the said ratchet-wheel beingmounted on a spring-pressed pivotallysupported arm and adapted to carrythe spring-pressed roll of the strip-transportingroll pair. Theelectromagnet AM serves to adjust the type-wheel O O axially on itsshaft in order to bring the second disk 0" of the same into operationwhen required.

Since, as already mentioned, the magnet AM is magnetized on the firstmovement (attraction) of the armature A of the magnet TM, but remainsdemagnetized during all the following vibrations of this magnet, owingto the fact that the fiat spring X is out of contact with thecontact-making tooth Z of the disk V, it will be evident that AM canonly be operated by the first current impulse of the local circuit, andonly then on the condition that this impulse, although short, is of acertain duration, the armature being adjusted to move somewhat slowly.The attraction of this armature will, however, only take place when thesigns are telegraphed which are opposite the metal strips of thekeyboard, in that in this case the pointer will be placed on the metalstrip, at which moment its speed of movementis zero, which will cause asomewhatdonger contact, and consequently line-current, although thepointer may be immediately moved at a greater speed along the edge ofthe base-plate A. Thus this first and somewhat-longer impulse is the'sole means of magnetizing the magnet AM by the aid of the local current25 to 28, 19, 18, 17, 29, to 33. The axial movement of thetypewheelresulting therefrom will be seen from Fig. 3. As soon as the wheel hasbeen moved a spring-pressed pawl w", mounted on the type-Wheelshaft,comes into engagement with a hook :20 of the type-wheel andcouples the same in this position. On the return of the wheel to itsinitial position the pawl w" is disengaged by a stationary pin 2, whichit strikes as the wheel returns. Thus it will be clear that the signscorresponding to the metal strips of the keyboard will have to be on thetype-wheel 0, while those corresponding to the insulating-strips will beon the wheel 0. Thus it will be clear that since two typewheels areemployed which may be brought into operation as required, according towhether the pointer is placed on a metal strip or on anon-conducting-strip, (in which latter case the first impulse will beshort, as the pointer passes rapidly over the same, having started on anon-conducting-strip,) the num ber of impulses necessary to produce thesigns will be only half of those which would be required were only onetype-wheel required. The capacity of the telegraphic type-writer willthus be nearly doubled for the same amount of current.

Although in the specification the non-conducting parts have beendescribed as ebony, it will of course be clear that they may be made ofany suitable non-conducting material.
